Title: Electric resistance heating element and the production thereof
IPC: H05B3/14
Filed: 1975-03-27
Abstract: 1496956 Extruded electric resistance heating element S KIYOKAWA 27 March 1975 [29 March 1974 (2)] 13022/75 Heading B5A [Also in Divisions H5 and C3] A heating resistor comprises a powder conductor in an insulating thermoplastics resin, wherein the powder is concentrated in the neighbourhood of the surface of the resistor. This is achieved by rapid cooling of a molten mixture of up to 40% carbon powder in a molten resin selected from the group, polyethylene, polypropylene, ethylene and vinyl acetate copolymer, polyvinylchloride and polyamide. The mixture is extruded and shock (rapid) cooled with gas or liquid (water), whereupon the conducting powder tends to migrate to the surface. The body is extruded either as a solid cylinder (Fig. 5) or hollow cylinder (Fig. 7), and flattened or as a flat sheet (Figs. 8, 9, not shown). Electric supply leads 3, 4 are incorporated during extrusion so that after the subsequent pressing flat between rollers 23, Fig. 5, 31, 32 Fig. 7, the leads are parallel to and adjacent the opposite edges of the elongate strip. Four (or more) parallel leads may if desired be incorporated (Fig. 3, not shown). By stretching the resistor as it cools, between pair of rollers or between rollers and the extrusion die, and by irradiation, the properties, including electrical properties, of the resistors may be altered as desired (Fig. 6, not shown). The resistor is enclosed in a non-conducting cover (2, Fig. 2, not shown) with leads 3, 4 connected to terminals (5, 6) mounted on the cover (2).

Abstract: 414,478. Spray - producers. STEVENSON, G. A., 3, Richmond Villas, and THOMAS, W. J., Tawelfa, Clasemont, Morriston, both in Swansea. May 4, 1933, No. 13047. [Class 69 (iii).] In an apparatus for spraying paint &c. air and liquid are mixed in the nozzle prior to their passage through a flat flared or fan-tailed orifice. The valves are operated by a compound lever device so that air is admitted before and shut off after the liquid and the liquid supply may be adjusted relatively to the trigger position while the gun is in operation. The apparatus comprises a butt member 1 having an air supply connection thereto and a barrel member in the front of which is secured a nozzle cap 6 having a fan-shaped orifice 8. The forward end of the barrel has a large bore 9 communicating with a smaller bore 9<a> in which is screwed a member 11 forming a liquid nozzle, the end 12 of which projects into the cap 6, and formed at 13 with an external hexagon surface, the corners of which nearly contact with the bore 9. Liquid is supplied by a pipe 15 and controlled by a needle valve 16 which passes through a gland 26 and has secured at its outer end a member 28 slideable within an adjustable sleeve 29. The sleeve 29 has a seating 32 for a spring 35 which bears against a flange 34 on the needle valve and thus tends to close it. Rotation of the sleeve 29 causes it to engage the head 28a of a pin screwed into the member 28 and thus adjust the needle valve. A trigger 36 pivoted at 37 to the butt is connected by a link 39 to a lever 40 pivoted at 41. The link has a cam surface 43 engaging the spindle 44 of a spring-pressed valve 21 controlling the air supply and the lever 41 is forked at 42 to engage the needle valve spindle, the arrangement being such that the air valve is opened in advance of the liquid valve.

Title: Improved oxygen concentration process
IPC: C21B5/00
Filed: 1963-04-03
Abstract: The concentration of oxygen in air is increased by passing feed air through an adsorption zone preferentially adsorbing nitrogen, which zone is then desorbed at a lower pressure by dry air having a dew point less than 0 DEG  F., flowing in the opposite direction, the feed air being subsequently re-introduced.  The dry air which may be used at 0-150 DEG  F. preferably 30-100 DEG  F., may have a dew point less than -200 DEG  F., e.g. dry CO2-free air of dew point less than -300 DEG  F.  The adsorption zone may work at 0 to 200 p.s.i.g. preferably 30 p.s.i.g., while desorption may be at 0 p.s.i.g.  The oxygen concentration of the air may be increased to 22 to 60 volume per cent by this process, preferably 30 volume per cent.  In a specific embodiment two beds of molecular sieves are used alternately on adsorption and desorption phases, the beds being dried by passing hot dry air through at 500 DEG  F.  After adsorption and prior to desorption, the pressure in the two beds is equilibrated by means of valves.  The process may be modified by attaching thereto a system for supplying dry air; alternatively, an adsorption zone may have a section for drying air and another for oxygen fractionation.  For continuous operation, at least 2 pairs of beds are used.  The reduction of pressure of the adsorption zone may altenatively be accomplished using a reservoir zone or by immediate depressuring to the low desorption pressure.  The use of the product stream, for blast furnace application, is disclosed. The adsorbent may be a zeolite molecular sieve having a pore diameter of 13A DEG , 10A DEG or 5A DEG . Specification 850,443 is referred to.
